How many needles make up a mosquito proboscis?

Explanation:
Understanding mosquito mouthparts means recognizing that the proboscis is made from six slender stylets. Two of these are the mandibles and two are the maxillae, which form the piercing needles that stab into the skin. The remaining two structures, the labrum and hypopharynx, help guide saliva and form the central channel through which blood is drawn. Together, these six components make up the mosquito’s proboscis, so the number of needles is six.
